Constant-temperature controller for compost fermentation

Abstract

The invention provides a constant-temperature controller for compost fermentation. The constant-temperature controller comprises an outer box wall, a constant-temperature fermentation tank is fixedly connected to the interior of the outer box wall, the outer box wall comprises a heat preservation interlayer, the heat preservation interlayer is fixedly connected to the surface of a bottom plate of the outer box wall, the heat preservation interlayer is arranged between the outer box wall and the constant-temperature fermentation tank, a water tank frame is fixedly connected to the heat preservation interlayer, and a heat source energy storage set is fixedly connected to a water tank frame of the outer tank wall. A constant-temperature reversing mechanism is arranged on the side face of the heat source energy storage set and connected with a waste heat recovery assembly and a heating assembly in parallel, and four heating branch pipes are connected between two main pipelines of a heating pipe in parallel. In the four-stage fermentation process, the waste heat of the last round is stored and used for the temperature rising stage of the next round of one-stage fermentation, heat source energy storage in the later stage of fermentation can be achieved and used in the initial stage of fermentation, energy recycling is achieved, energy recycling and effective utilization are improved, energy consumption is saved, and cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of compost fermentation equipment, and more specifically relates to a constant temperature controller for compost fermentation. Background technique [0002] Composting is a method of aerobic fermentation to treat organic waste. It is mainly a process of transforming organic matter into fertilizer through the fermentation of microorganisms under certain C / N ratio, aeration conditions and water under artificial control. For fertilizer and soil improvement, when the composting fermentation equipment adopts a multi-stage fermentation method during the composting fermentation, a heat source is required to heat the fermentation tank in the first stage of heating, and the second, third, and fourth stages of fermentation will generate heat and heat up. [0003] For example, application number: CN201610801111.1 The present invention discloses a process automatic control method for rapid aerobic fermentation process ...
